array_walk an anonymous function

Question

Is there a way I can get this array walk with my anonymous function to set the values?

$url = array('dog', 'cat', 'fish');  array_walk($url, function(&$value, &$key) {     $url[$key] = str_replace('dog', '', $value); });  echo '<pre>'; print_r($url); echo '</pre>'; 

Answer 1

You are already passing the value by reference, so just do the following:

array_walk($url, function(&$value, &$key) {     $value = str_replace('dog', '', $value); });
